Electrical Power Systems (EPS)

Electrical power systems provide turnkey solutions for hydropower plants, including engineering, design, and supply of electrical and balance-of-plant equipment that allows turbine and generator to operate efficiently.

EPS covers the complete range of project processes, including system engineering and project management, up to final handover to the customer.

Assisted by its many experienced engineers, who have a long history of projects executed successfully, ANDRITZ HYDRO provides the entire EPS equipment from a single source in order to guarantee that the customer receives a fully functional power plant system customized to his needs.

The equipment range includes low-voltage, medium-voltage, and high-voltage equipment for indoor and outdoor applications; power and instrument transformers; HV substations; back-up diesel generation and battery systems; grounding and lightning protection; fire-fighting and alarm systems; lighting and small power systems; the complete cabling and interconnection system up to transmission line links, as well as ventilation and air conditioning for the power plant.

All equipment will be integrated into the automation, control, and protection system of ANDRITZ HYDRO, including the interface management to other auxiliary systems.

In addition, EPS provides engineered solutions of highest quality for special applications, such as pumped storage plants, by integrating starting frequency converters as well as AC excitation systems for adjustable speed plants.

The client benefits from worldwide equipment sourcing, taking account of his expectations and quality requirements.

The work will be performed according to internationally accepted standards, e.g. IEC, ANSI, IEEE, NEMA, also respecting national requirements.

Main EPS tasks
